Answer:
electrons have negative charge
When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)
Answer:
Most protists are unicellular. You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms. It is because, unlike bacteria, protists are complex cells.
Also:
Among these three main types of archaea are some subtypes, which include: Methanogens — archaeans that produce methane gas as a waste product of their "digestion," or process of making energy. Halophiles — those archaeans that live in salty environments.

Explanation:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. ... Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
